Paying for efiling PA State Taxes with Credit Card through TurboTax

I have been trying for 2 days to pay the PA State Filing fee of $24.99 to efile my state taxes when requested by TurboTax program. I have completed the payment details with two different credit cards, and after over 10 tries, it still will not go through. I have been efiling through TurboTax for many years and have never had a problem with this. I do not get any error messages. The "continue" button is grayed out with a red circle with a line through it. And, yes, I have completed all of the information, including the security code.

Please help!
